Know before you buy
Yes, this basket is designed for standard 58mm portafilters. It features a 70mm border diameter and a 60mm body diameter, making it compatible with most professional-style espresso machines.
We recommend using a 58.4mm tamper for the best results. This size ensures a precise fit against the walls of the basket, helping to prevent channeling and ensuring an even puck density.
The unique hole pattern is engineered to direct the flow of water toward the center of the basket. This promotes more uniform extraction, which typically results in a sweeter cup with reduced acidity compared to standard baskets.
While it performs exceptionally well with medium to dark roasts, its precision design is versatile enough for any roast profile. However, you may need to adjust your grind size slightly finer to account for the high-flow nature of the precision holes.
This basket is specifically designed for use with bottomless (naked) portafilters. Because it is a ridgeless, flat-bottomed basket, it is optimized for clean puck expulsion and visual monitoring of the extraction.
The electro-polished finish makes the basket resistant to coffee oil buildup and easy to rinse. We recommend a simple hot water rinse after use and occasional soaking in a dedicated espresso machine cleaner; it is not recommended for dishwasher use.
